What is a Buy-to-Let mortgage?

A Buy-to-Let mortgage is specifically designed for properties you intend to rent out rather than live in yourself. It’s distinct from a residential mortgage and comes with its own set of criteria and considerations. It’s important to note that Regulated Buy-to-Let mortgages apply when you plan to rent to an immediate family member.

Tailored Buy-to-Let mortgage advice for every landlord

The Buy-to-Let market is vast and ever-changing, with diverse criteria from numerous lenders. This is why personalised advice is so valuable, regardless of your experience level. We offer expert guidance for a variety of landlord scenarios:

If you’re a first-time landlord, starting your journey can be exciting but also daunting. We recommend:

  • Researching developing areas: These locations can offer lower purchase prices and greater growth potential.
  • Understanding rental yields: Ensure projected rental income can comfortably cover potential mortgage payments.
  • Assessing your finances: Confirm you have the necessary funds to purchase, maintain, and manage properties.
  • Starting small: A less expensive property can minimise risk and help you gain valuable experience.

Our expert Buy-to-Let mortgage advisors can provide essential guidance as you embark on this new venture.

Becoming a landlord accidentally could happen through receiving an inherited property or through relocation. If you’re in this situation, a good place to start is understanding your legal responsibilities. Ensuring that you’re compliant with landlord regulations can help you to avoid potential pitfalls.

Becoming a landlord by accident can be overwhelming if it’s not your area of expertise. However, there are property management companies out there that can provide support in these situations.

Our mortgage experts can guide you through consent to let if you’re stuck and can’t sell your home. They are experienced with Let to Buy if you’re looking to move home whilst renting out the other, and as above, we can also help you with a longer-term solution which is Buy-to-Let.

You can count on us to provide clear, practical advice designed to support accidental landlords in navigating owning a property with confidence.

As a professional landlord with four or more Buy-to-Let mortgages [1] across all lenders, managing your portfolio strategically is key. Lenders require detailed information on your properties to ensure responsible borrowing.

Our Buy-to-Let mortgage advisors are experts at navigating the complexities of lender criteria, from loan-to-value ratios (LTVs) to rental stress tests, to ensure you have the most competitive mortgages in place and can strategically release equity for growth.

As with someone who is new to Buy-to-Let, as an overseas landlord, it’s important to understand the market where you want to invest. Our experts offer insight into important legal and regulatory aspects that may impact your investment decisions such as the Non-resident Landlord’s Scheme (NRLS).

You should be aware of regular changes in currency as this could mean that your rental income may vary. Opening a UK bank account could help to better manage these currency risks.

Property managers are perfect for those living overseas. They can help to manage your property or properties, or utilise property management software to help streamline your operations.

You can rely on Just Mortgage Brokers for expert guidance tailored to international investors.

Understanding your Buy-to-Let borrowing capacity

Understanding your borrowing capacity when it comes to Buy-to-Let mortgages gives you the insight you need to make informed financial decisions.

There are different scenarios that can affect both your monthly mortgage payments and the interest that you pay on a Buy-to-Let mortgage.

High deposit vs. low deposit

High deposits:

  • Deposit amount: £250,000 (50% of property value)
  • Property value: £500,000
  • Loan amount: £250,000
  • Interest rate: 3%
  • Loan term: 25 years

In this case, the borrower’s borrowing capacity is higher because they have a larger deposit. This reduces the risk for lenders and makes the borrower more appealing.

In cases like this, lenders may offer a lower interest rate due to the lower loan-to-value ratio (LTV), resulting in lower monthly mortgage payments.

Low deposits:

  • Deposit amount: £125,000 (25% of property value)
  • Property value: £500,000
  • Loan amount: £375,000
  • Interest rate: 4%
  • Loan term: 25 years

In this case the borrower’s borrowing capacity is lower because they have a smaller deposit. This increases the risk for the lender making the borrower slightly less appealing.

In cases such as this, the lender may offer a higher interest rate due to the higher LTV, resulting in higher monthly mortgage payments.

Different interest rates

Lower Interest Rate with a 25% Deposit:

  • Deposit Amount: £125,000 (25% of property value)
  • Property Value: £500,000
  • Loan Amount: £375,000
  • Interest Rate: 2.5%
  • Loan Term: 25 years

The lower interest rate of 2.5% results in more manageable monthly mortgage payments. The borrower’s borrowing capacity may be higher due to the reduced interest costs and lower risk associated with the lower LTV ratio.

Scenario 2: Higher Interest Rate with 25% Deposit

  • Deposit Amount: £125,000 (25% of property value)
  • Property Value: £500,000
  • Loan Amount: £375,000
  • Interest Rate: 5%
  • Loan Term: 25 years

A 5% interest rate introduces a much higher cost of borrowing. This also reduces the borrower’s borrowing capacity despite the same 25% deposit. Due to the reduced borrowing capacity, lenders may impose stricter criteria or offer less favourable terms due to the higher interest rate and associated risks.

These different scenarios show how deposit amounts and interest rates can influence borrowing capacity and affordability in property investment decisions.

The impact on your borrowing capacity

Deposit Amount: A higher deposit typically increases borrowing capacity because it reduces the LTV ratio, potentially lowering mortgage interest rates and monthly payments.

Interest Rates: Lower interest rates enhance borrowing capacity by reducing monthly payments, whereas higher interest rates decrease borrowing capacity due to higher monthly costs.

In summary, your deposit amount and interest rate play a crucial role in working out your borrowing capacity. A higher deposit generally allows for a larger loan amount and lower interest rates, while lower deposits may lead to higher borrowing costs and potentially stricter lending criteria. Interest rates directly affect monthly mortgage payments, influencing affordability and overall borrowing capacity. Use our mortgage repayment calculator to get a better understanding of what you might pay depending on your deposit and interest rates.

Choosing the right Buy-to-Let mortgage rate: fixed vs. tracker

Deciding between a fixed-rate or tracker-rate Buy-to-Let mortgage depends on your financial goals, ability to handle income fluctuations, and the current market conditions.

  • Fixed-Rate Mortgages: Offer stability and protection from potential interest rate increases, making them a good option for cautious landlords seeking predictable payments.
  • Tracker-Rate Mortgages: May offer lower starting interest rates and can be advantageous when interest rates are low. However, they carry the risk of increased monthly repayments if interest rates rise.

Our mortgage experts can help you assess these options and find the best mortgage deal for your specific needs.

Qualifying for a Buy-to-Let mortgage

To qualify for a Buy-to-Let mortgage, you’ll need to meet specific criteria set by lenders. While requirements can vary, common criteria include:

  • Minimum age: Most lenders require applicants to be at least 21 years old.
  • Deposit: A minimum deposit of 25% of the property value is typically required.
  • Rental income projections: Lenders usually require the projected rental income to cover 125-145% of the mortgage repayments.
  • Affordability assessment: All lenders will assess your ability to cover mortgage payments, especially during potential vacant periods.
  • Homeowner status: Many lenders prefer, or even require, that Buy-to-Let applicants already own their own home.

It’s important to remember that this list isn’t exhaustive, and criteria can differ significantly between lenders. We highly recommend speaking to an expert Buy-to-Let mortgage advisor to guide you through the process.

Maximising your Buy-to-Let profits

Several strategies can help you maximise your Buy-to-Let profits:

  • Property improvements: Modern amenities, fresh paint, and updated kitchens/bathrooms can attract higher-paying tenants.
  • Optimising rental income: Regularly review local rental rates to ensure your rent is competitive yet maximised. Offering furnished rentals can also provide additional income.
  • Effective tenant management: Retaining good tenants through open communication, prompt issue resolution, and modest rent increases on renewals can reduce costly void periods.
  • Preventative maintenance: Regular property inspections can catch and fix small issues before they escalate into expensive repairs, reducing long-term maintenance costs.
  • Energy efficiency: Investing in energy-efficient appliances and insulation can lower utility costs for tenants, making your property more attractive while reducing your overall expenses.
  • Self-management: If feasible, managing the property yourself can save on letting agent fees.

Buy-to-Let mortgage lenders

While specialist Buy-to-Let lenders still offer a dynamic range of products and criteria, many high street lenders now also provide numerous options.

The “best” Buy-to-Let mortgage lender is ultimately the one that offers the right criteria for your individual requirements and situation and then, in turn, the most appropriate mortgage scheme. With all lenders having different criteria for their Buy-to-Let mortgage qualification, you will need to ensure you meet all of these to qualify.

Some of the criteria will likely be:

  • Your deposit or existing equity.
  • Whether you are a homeowner or a first-time buyer.
  • If you own existing Buy-to-Let properties or are a first-time landlord.
  • The type of Buy-to-Let: Regulated Buy-to-Let (renting to immediate family) or Consumer Buy-to-Let (for accidental landlords, e.g., inherited property).
  • Your credit history.
  • Projected rental income and how it fits affordability for the loan amount required.
  • Your personal income (PAYE salary or self-employed income).

The benefits of using a Buy-to-Let mortgage broker

Navigating the complex Buy-to-Let mortgage market, with its vast number of products and varying lender criteria, can be overwhelming. This is where the expertise of a Buy-to-Let mortgage broker becomes invaluable.

Why Seek Advice?

While you might have the confidence to arrange your own mortgage, many people benefit from expert guidance. Seeking advice ensures you obtain the most appropriate Buy-to-Let mortgage for your individual circumstances. This provides peace of mind and can be hugely financially beneficial throughout the lifetime of your mortgage.

The market is constantly changing, not just in rates but also in lender criteria. Whether you’re a first-time landlord or a professional portfolio landlord, seeking advice gives you the confidence that you’re making the best decision.

Buy-to-Let mortgage Broker Fees

When exploring Buy-to-Let mortgage advice, you’ll find that, while initial consultations are often free across the industry, some brokers, like us, charge fees for their services upon proceeding. Regulations require full transparency regarding these fees.

How broker fees are structured:

  • Calculation methods: A broker’s fee is typically calculated as a percentage of the total loan amount (often around 1%) or as a fixed fee, which can vary from £500 to £1,000.
  • Payment source: It’s common for brokers to receive commission from the lender, a fee from the borrower, or sometimes both. If a fee is solely based on a percentage paid by the borrower, the commission received from the lender is often rebated.
  • Higher BTL fees: Buy-to-Let broker fees tend to be a little higher than those for conventional residential mortgages.

Other potential costs in the mortgage chain: It’s important to be aware of other charges within the mortgage chain that are not the broker’s direct fees. These might include, for example:

  • An application fee (which may cover a valuation survey).
  • A booking fee (paid to the lender to secure an interest rate).
  • Transfer fees.
  • Legal fees for your solicitor.

Ultimately, every professional involved will require payment for their services. While a figure might appear to be a saving, it could be recuperated in a more subtle way, such as a slightly higher interest rate. Remember, brokers are obliged to act in your best interests, not solely for their profit, guiding you to the most appropriate mortgage for your needs.

Frequently Asked Questions

You will typically need a minimum deposit of 25% of the property’s value for a Buy-to-Let mortgage.

Yes, Buy-to-Let (BTL) mortgages are generally more expensive than standard residential mortgages for several reasons:

  • Higher interest rates: Lenders perceive BTL mortgages as higher risk due to unpredictable rental income and potential vacancies.
  • Larger deposits: A minimum of 25% is usually required, compared to 5-10% for residential mortgages, reflecting the increased risk to the lender.
  • Stress testing: Lenders apply more stringent stress tests, assessing whether rental income will cover mortgage payments by a significant margin (typically 125-145%).
  • Limited product options: Fewer BTL mortgage products exist, potentially leading to higher costs due to less competition.

The costs associated with a Buy-to-Let property can include:

    • The costs of buying the property (e.g., stamp duty, solicitor fees).
    • Acquiring necessary safety certificates (gas, electrical, energy performance).
    • Letting agent fees (if you use one).
    • Mortgage payments.
    • Landlord insurance and building insurance.
    • General property maintenance.

For a full breakdown, consult a comprehensive guide on Buy-to-Let costs.

As a landlord, you have significant legal responsibilities to maintain your property and ensure the safety and well-being of your tenants. Key responsibilities include:

  • Keeping properties safe and free from health hazards.
  • Ensuring all electrical and gas equipment is safely installed and regularly maintained.
  • Providing an Energy Performance Certificate (EPC) for the property. New regulations will soon require rented properties to have an EPC rating of C or above.
  • Ensuring your tenant has the right to rent your property (in England).
  • Providing tenants with the “How to Rent” checklist at the start of their tenancy.

Yes, Limited Company Buy-to-Let mortgages allow you to secure mortgages for properties using a limited company structure instead of your personal name.
